In my defense, I’ve had a phone hang up or do weird stuff because it couldn’t tell the difference between a fingertip and an earlobe way too many times. Like, a shitty phone has nearly altered the course of my life because of this, and that’s not okay.
Sounds like they might be drying out, maybe while they’re waiting to be cooked. You can keep them under a moist towel while waiting if that’s the issue. They might also be cooking too long. I don’t have a great sense of what doneness looks like for tortillas, but I imagine knowledge mostly comes from experience.
